JFET_V2_N2_A2 External Hardware Security for Steganography Suresh D.S. V. Udayashankara Journal on Future Engineering and Technology 2230 – 7184 2 2 17 22 Hardware Security, Steganography Many steganographic techniques are extremely vulnerable to attacks, and even detection of the information in the image file is quite easy. So a microcontroller is used for the sake of security where it transmits a pre-programmed password at the beginning of each process. The steganalysis algorithm continued only if the received password is correct at the destination, otherwise retrieving the secure information from the cover image is impossible.
